ICE-CREAM-CON E MACHINE.

To all whom it may concern:

Be it 'known that I, THoM s G. PERKINs, a citizen. of-the United States, residing at- Seattle, inthe county of King and State of Washington, have invented certain new and useful Improvements in Ice-Cream-Cone Machines, of which the following is a specification.

This invention has for its object the im} provement in that class of machines wherein Y ice-cream cones are manufactured by first cooking the material in thin cakes and subsequently rolling the latter about a suitably shaped former, and contemplates a machine requiring but little manual labor and :pro-

ducing cones of a-uniform" size and thickness, to which ends the invention consists in certain novel features of construction and combination of parts, as-Will be hereinafter 'ence numerals denote described and claimed.

Insaid drawings, Figure '1 is a front elevation of an ice-cream cone making machine embodying my invention. Fig. 2 is view thereof with parts broken away. Fig. 3 is alongitudinal vertical Section. Figs. 4 and 5 are cross sectional views taken through -1-4; and 5-5 of Fig. 2. F ig. 6 is a detail front elevation showing the cake rolling devices to an enlarged scale. Fig. 7 is an end view of the same and Fig. 8 a plan View.

Fig. 9 is a detached elevational view of the pin employed in coupling the power driven cone of the cone-rolling devices with the driving pulley therefor. Fig. 10 is a per,- spective view of the feed. valve and devices for controlling the same;

In these. drawings, where similar refercorresponding throughout, 1 designates a casing which is supported upon a suitable frame. Extending transversely through the casing near its opposite ends are shafts 2 and 2' for sprocket wheels, seeFig. 3, which may each be formed of apair of. spaced spiders constituted of radiating spokes 3 connected near their outer extremities by tie-bars 4. Said sprocket wheelsserve as carriersfor a chain, so to speak, comprised of batter-cooking irons. These irons are disposed in pails, 5 and 5, which are respectively connected at. the rear by hinges 6; and the adjacent irons 5 are connected from their ends by hinges 7 to accommodate the travel of the chain when passing about the aforesaid sprocket wheels. The lengths of the irons 5 are such that theyv will fit between the wheel spokes 3 and seat Specification of letters Patent.

portions of the spokes engage the chain in the interstices between the successive pairs of irons. Intermittent motion is afforded said chain by means of aratchet wheel 8 mounted on the end of the sprocket wheel shaft 2 being actuated by a pawl 9 carried on an arm 10 loosely mounted on the shaft and which, in turn, derives its motion through the medium of aconnecting rod 11 from a crank pin 12 provided on a disk Wheel 1.2 mounted on the end of -a transversely arranged shaft 13. The latter, as illustrated in Figs. 1 and 2. is rotated from a power driven shaft 14 and an intermediate shaft 15 by means of a beltl6 passing about pulleys 14' and 15 on the last named shaft, and by spur gears 17 and 17 operatively connecting the intermediate shaft with shaft 13. The cooking irons, 5 and 5, respectively, are provided at the fro-nt and rear thereof with wheels 18 and 18 19 disposed at suitable elevations .to support the irons horizontally in their travel between The ends of the track rails 19 are curved downwardly, see Fig. 3, in order that the wheels 18 of the irons 5 will be uided onto the straight middle portions of these rails. The other rails, 19, are curved upwardly at their end and are arranged'to support the wheels 18 in traveling about the lower peripheries of said sprocket wheels for the purpose of preventing the irons 5 swinging downwardly from the irons 5 about the hinge connections 6. 20 represents a pipe for supplying fuel gas to perforated branch pipes or burner ele ments 20 provided within the casing and whereby a fire is produced to heat the irons 5 and 5'1 Said chain of irons is driven so as to cause the upper horizontal portion, or lead, to traverse the machine in the direct-ion indicated by arrow :0 in Fig. 3. Near the beginning of such traverse movement the then upper irons 5 are tilted upwardly and so maintained to remove a cooked cake from the successively exposed irons 5 and then receive a supply of batter on the same to be cooked during the followingcyole of the chains travel. To attain these ends, there is provided at the rear of themachine a longitudinal shaft 91 which is rotated in unison by means'of a pair of On the remote end of shaft 21 from said gears is a'disk 23 carrying a while the protrudingwhich re-* i spect1vely track on longitudinal rails 19' and disposed horizontally and then is inclined downwardly to terirons are being heated crank pin 23' which is connected by a rod 24 (see Fig. 4) with an arm of a lever 25 which is fulcrumed at 26.130 a bracket element 26 of the machine frame. Hingedly connected to the other arm of this lever is a hook 27 which is arranged to engage at their front edges irons 5' as the same are successively presented and then individually tilt them upwardly as the hook controlling lever is actuated by the crank in 23 in each revolution of the same. The above described upward tilting of an iron occurs during an interruption in the travel of the chain of irons.

Devices are provided to relieve the hook 27 of an iron when elevated and retain the iron thus elevated ,until a cake has been removed from an iron 5 and the latter sequently supplied with a charge of batter. Accordingly, I employ a short length of elevated track-rail 28 which, at its right hand end and for a distance therefrom, is at the requisite height minute in proximity to the front track rail 19. The left hand end 28' of the elevated rail is hinged to the main portion to enable such end to be tilted up clear of the traction wheels belonging to the iron 5' to pass unobstructedly thereby when it is desired to allow of the passage of such iron in an unelevated condition-as, for example, when the preparatory to the cooking of the batter into cakes in one sta e of the machines operation. Immediately ahead of and normally coextensive with said advance end of the elevated rail is a tongue 29 which is fixedly connected to a shaft 30 journaled in bearings provided in an upstanding element 31 of the machine frame. Said shaft is provided with a crank arm 30 which is connected by a link 32 (Fig. 5) with an arm 33 of a bell crank lever whose other arm 33 carries a roller 34 which engages against the periphery of a cam 35 mounted on the shaft 21. This cam is con tinuously rotated during the operation of the machine and is adapted to effect the periodic lowering of the tongue 29 from the position in which it is represented in Fig. 1 to that in which it is shown in Figs. 2 and 3 and occurring directly followin the bringing of an iron 5 into its uptilte position. The previously raised traction wheel 18 is guided'by the tongue onto the elevated rail 28 in the next forward travel of the chain. The cam is constructed to allow the unbalanced weight of the link 32 to effect the upward swinging of the tongue 29 to be clear of a wheel when the iron by which it is carried is being swung upwardly through the agency of the hook 27, as above explained.

The batter-feeding apparatus will now be described.

sub- I 36 is a batter-containing vessel supported by framework 37 at a suitable height at the front of the machine and is provided with a drain-cock 38 which. furnishes a regulated flow of batter into the upper end of an inclined trough 39. The lower end of this trough is located to be approximately above the centers of'the irons 5 when the latter are successively stopped. Atsuch lower end of the trough is a batter-dischar e opening controlled by a valve 40 (see igs. 2, 4 and 10) connected to a rod 41 to swing about the axis thereof. The rod 41 is journaled in bearings provided in lugs 42 extending from the trough structure and has an arm 43 which, in effect, coiiperates with the arm 40' of the valve to serve as a bell-crank.

44 is a lever fulcrumed to a support 45 "secured to or made a part of the machine frame. The lower arm of the lever 44 is provided with a slot to receive an operating pin 46 protruding forwardly from the arm of abell-crank lever 47 whose other arm suspends a weight 47'. This bell-crank 47 is mounted at the front of the machine on a rockershaft 48 which extends through the machine casing and carries an arm 49 at its rear end, shown in Fi 2 and 4. s

50 is a cam mounte on shaft 21 and, as illustrated, is in the nature of a disk with a protuberance 50' which acts against the arm, or preferably against an anti-friction roller 49' thereon, to swerve the same away from the face of the-disk portion of the cam in each rotation of the shaft 21 and in opposition to the referred to weight 47' to e set the rocking motion of the bell-crank lever 47 through the medium of the shaft 48.

The upper arm of the lever 44, in the alternate oscillatory strokes thereof, operatively engages the shaft-arm 43 by a stud 51 and a screw tends through a threaded hole in an attachment 53 pivotally connected at 54 to the lever arm, as best shown in Fig. 10, so that by swinging the attachment upwardly about the pivot '54, the screw 52 is withdrawn from its operative relation with respect to the arm 43 when thelever 44 would vibrate without affecting the valve 40'which would then remain in closed position. By adjusting' the screw 52 to advance its point toward or retract it from the stud 51 the space for the arm 43 of the valve shaft is diminished or increased resulting in more or less motion to the lever 44 independently of the arm affording means for regulating the amount ,of the valve opening for a desired quantity 52 carried by the lever armat opposite sides of the shaft arm. Said screw exing functions become operativenamely, the tilting up of one of the irons, the devices for swinging of the track-tongue to and from its operative position and the valve regulation of opening from the batter-' trough to supply a charge of batter upon the surface of an iron 5. When an iron 5 is tilted up, the cake thus exposed is removed by the operator and is transferred manually across the top' of a table 56 in front of the operator to be automatically rolled into a conical shape by the mechanism which will now be described. I

57 is a horizontal shaft extending longitudinally of the machine in front of the table 56 and with its aXis at about the level on a cone 58 which serves as the former about which the cakes are successively rolled. Extending into the cone for a distance from the apex is a diametrically arranged slot 58. The cone-shaft is journaled in bearings provided in spaced standards 59, of the machine frame and upon the opposite end of this shaft from'. the cone is a loose pulley 60 which is driven at a relatively high speed from a pulley 61 on the shaft 14 by means of a belt 62 which is led by guide pulleys 63 and 63. In proximity to the pulley 60 is a wheel 64 rigidly secured to the shaft 57, and is provided with means engageable by a stud 60 (Fig. 6) on the wheel whereby the wheel may be united to the rotating pulley for imparting corresponding motion to the shaft 57 and cone 58. consists of a headed pin 65 which extends through an eccentrically disposed bore in the wheel. 66 is a spring acting between the head of the pin'and an annular shoulder provided in said bore to urge the head end of the pin within the'orbit of the pulleystud 60 to transmit the abovementioned rotation of the pulley to the cone. Provided in the periphery of the pin is a helical'ly arranged groove 67, (see Fig. 9) terminating at an end 67 disposed radially with respect to the pin axis.

68 represents a bolt guided for vertical movements in brackets 69 formed on a depending member 59 of the frame. Reciprocatory motion is imparted to said bolt from alever 70 extending between projections 68 on the bolt and fulcrumed to a pivotal pin 71 on the frame member 59 The upper end of said bolt is formed with a flattened port-ion 68 which, in the elevation of the bolt enters the pin groove 67 and contacting with the helical walls thereof causes the pin 65 to be shifted in opposition to spring 66 endwise from the stud 60 resulting in the driving devices for the shaft of said cone becoming inoperative. The momentum ofthe previously driven shaft 57 and the parts associated therewith prolongs the rotary motion of the same until the wheel is against a pin 80 provided Said means advantageously arm 87 which is arrested by the groove end 67 of pin 65 encountering the. bolt. This stoppage occurs when the aforementioned slot 58 of the cone is in the horizontal position in which it is illustrated'in Fig. 6. The lever 70 is actuated from a through the medium of a connecting rod 73.

Having its axis in a vertical plane with the axis of the cone shaft 57 is a superposed shaft 74 journaled in a yoke. 75 and movable vertically in guideways 76 provided in the upper ends of the standards 59. 'At or about its midlength. the yoke 75 is connected by. a link 77 with the upper arm 78 of a lever which is fulcr'umed intermediate its length by a pivot 79 to the frame, while its other arm extends downwardly to present a cam face 78 for engagement upon the lever 70. To one side of said yokes connection with the link 77 it is connected by an extensible spring 81 with a standard 59, as shown in Fig. 6, said spring tends to maintain the cam face 78 of the lever against the pin and likewise to tilt the yoke so as to yieldingly hold the cone 74 which is mounted on shaft 74 in the position in which it is seen in Fig. 6.

A conoi'dal shaped roller 83 is mounted on the end of the lever 70 and is arranged to be swung therewith from the position in which it is illustrated in Fig. 6 to that shown in Fig. 1 and into proximity of and extend a distance in front of the point of the cone 58.

In transporting a cake across the table 56 from thecooking irons to the cone 58, about which circular cakes are successively wound, the edge of a cake is introduced into the cone slot 58 in such a position longitudinally of the cone as to produce ice-cream cones from the cake of uniform configuration and proportioned to afford pedal 72, Fig. 1,

a maximum strength from the material utilized.

Referring to Figs. 2, 7 and 8, the devices for directing the cakes to the cone slots and locating them consists of guides which, for convenience of explanation, will hereinafter be designated as the upper, lower and edge guides. Said upper guide comprises a plate 84 secured to the arm 84 of a bell crank lever which is pivotally connected at 85 to the machine frame and the other arm 84 is connected by a rod 86 with the lever 70 so that, when the latter is influenced to cause the cone 74 and the conoidal roller 83 to be removed from the cone 58, the guide plate 84 is brought into proximity of the periphery of cone 58 as in Fig. 2. The lower guide consists of a plate 87 secured to an pivotally connected by pin 88 to the frame to swing horizontallyto and from the cone 58. Such swinging motions are attained through the instrum'entality of an oscillatory element 89 pivoted intermediate its length to apin 90 and having at one end a tooth 89 which engages in a notch 87 2 of the arm 87 while its other end 5 is bifurcated to straddle a pin 91 upon the arm 84' of the bell-crank which carries said upper plate. By thus operatively connecting the upper and lower plates it is evident that they will always be swung in unison. The other, or edge-guide, consists of a vertically disposed plate 92 suspended near its top by a pin 93 from a frame element 94. This late is brought into operative osition (see Fig. 7 by the weight thereo and is swung into inoperative position (see Fig. 4) by being pushed by the upper ide when the same 15 swung away from t e cone 58. The edge guide is desirably of a length so as-to extend below the table 56.

The operation of the invention ma be explained as follows: The action and mo- .tions of the cooking irons 5, 5 and the devices for tilting upwardly the irons 5' as they are successively stopped in their 'stations beneath the hook 2-7 will, it is thought, be understood from the foregoing description. As will also be understood the function of the superposed track rail 28 and the operation of the movable end connections 28 and 29 of the same; as well as the batter feeding devices which are illustrated rincipally in Figs. 4 and 10. The batter is discharged u n each of the irons 5 as they are stop below the outlet end of the supply trough 39. The batter, as delivered, sprea 3 upon an ironinto the form of a circular cake. After a previously uptilted iron 5 has lowered throu h the ofiice of the inclined portionof the real 28 upon the batter-charged iron, it is carried in such closed condition through the" circuit of its travel until -it-arrives atthe osition where the then upper iron 5 is again uplifted throu h the instrumentality of the hook 27. T e irons, meanwhile, have been subjected to the heat generated b the s from the burners 20 to thorou b y coo the batter. When an iron 5' has en uptilted, as above noted, the operator removes the cake from'the com- 50 plementary iron 5 and transfers it across the table against the guide 92 and between the guide plates 84 and 87 which have been .moved into the ositions in which they are represented in Fig. 7 through the power exercised by the Wei ht 73 (Fig. 1) subse uent to the with rawal of foot ressure rom the treadle to influence the ever 70 which not only afiects the guides but also causes the stoppage of the rotation of cone 58 and the movements of the cone'74 and wheel 83 into the positions where-at they'are shown in Figs. 6 and 7. The cake being guidedby the above mentioned guides has its advanced edge introduced into the cone to slot 58', and into position so that the cake rolled 0r wound about the cone 58 the lever 70 is influenced to restore the several eleiments into the relative posit-ions in which they are shown in Fig. 6 and the previously moved from the cone 58.

when rolled will rotrude beyond the point of the cone 58, w ereupon .the operator, by pressing the treadle downwardly, overcomes said weight and moves the lever 70 and associated parts from the positions in which they are shown in Fig. 6 to those which they occupy in Fig. 1 to accomplish the operations contributory to the winding of a cake about cone 58, to-witthe lever 78 is swerved by having the pin 80 brought into recess 78 of the lever and the shaft 74 and cone 74' are moved downwardly by the sgiring 81, the wheel 83 is moved upwardly irectly on lever 70, the bolt 68 retracted from pin so that the s ring 66 can effect the endwise movement 0 the pin to operatively couple the wheel 64: with the driving pulley 60 to turn the cone 58 for winding the cake about the latter. During the winding of the cake the guides are withdrawn, as represented in Fig. 4. In the winding of a cake an ed e of the same is retained within the cone s 0t 58 so that the cake will be drawn about the cone, while the conical wheel 83 serves with the cone 74: to form the protruding portion of the cake into a solid pointed. mass to improve the appearance of the product and also render the same nonleakable at the point. After a cake is completed .ice cream cone is manually re- What I claim as my invention, is-
